When you see something that requires you to slow down or to stop, it’s always good to let other drivers know you’re stopping. 

When you press the brake pedal and your brakes start to slow you down, your brake lights turn on to indicate that you’re slowing down. As you do a lot of stopping and starting, these lights get a real workout. As a result brake lights stop working and need replacing quite frequently. 

It is also a part of New Zealand law that your ‘stop lamp’ emits a light when under braking. Therefore, to adhere to the NZ road rules and protect your car as well as other motorists, you should ensure that your brake lights are in perfect working condition.

What is a brake light bulb?

A brake light bulb is typically a 12V bright white bulb that illuminates through a red lens. It’s fitted to a socket providing it power when the circuit is completed by you touching the brake pedal. It is a fairly simple light with a very important job. 

When illuminated, it gives off a very strong, bright light that will draw other motorists attention even in the middle of the day. This is great for safety but as a result it gives off a lot of heat. If you were to touch a bulb while it was on, you’d get burnt. This can lead to the filament burning out over time.

Why do you need a brake light bulb? 

Your brake light tells everyone else that you’re slowing down or stopping. If other motorists don’t know you’re slowing down then it could lead to crashes. 

Clearly it has an important job and the government thinks so too! Brake light bulbs must be in perfect working condition by law. If they aren’t, you can be fined. 

So not only do you need a brake light bulb to protect your car, you also need them to protect your wallet and demerits.
